13 Chapter 2. Adjusting and using your monitor This section will give you information on adjusting and using your monitor. Comfort and accessibility Good ergonomic practice is important to get the most from your personal computer and to avoid discomfort. Arrange your workplace and the equipment you use to suit your individual needs and the kind of work that you perform. In addition, use healthy work habits to maximize your performance and comfort while using your computer. For more detailed information on any of these topics, visit the Healthy Computing Web site at: Arranging your work area Use a work surface of appropriate height and available working area to allow you to work in comfort. Organize you work area to match the way you use materials and equipment. Keep your work area clean and clear for the materials that you typically use and place the items that you use most frequently, such as the computer mouse or telephone, within the easiest reach. Equipment layout and setup play a large role in your working posture. The following topics describe how to optimize equipment setup to achieve and maintain good working posture. Positioning and viewing your monitor Position and adjust your computer monitor for comfortable viewing by considering the following items: Viewing distance: Optimal viewing distances for monitors range from approximately 510mm to 760mm (20 in to 30 in) and can vary depending on ambient light and time of day. You can achieve different viewing distances by repositioning your monitor or by modifying your posture or chair position. Use a viewing distance that is most comfortable for you. Monitor height: Position the monitor so your head and neck are in a comfortable and neutral (vertical, or upright) position. If your monitor does not have height adjustments, you might have to place books or other sturdy objects under the base of the monitor to achieve the desired height. A general guideline is to position the monitor such that the top of the screen is at or slightly below your eye-height when you are comfortably seated. However, be sure to optimize your monitor height so the line of site between your eyes and the center the monitor suits your preferences for visual distance and comfortable viewing when your eye muscles are in a relaxed stated. Tilt : Adjust the tilt of your monitor to optimize the appearance of the screen content and to accommodate your preferred head and neck posture. General location: Position your monitor to avoid glare or reflections on the screen from overhead lighting or nearby windows. The following are some other tips for comfortable viewing of your monitor: Copyright Lenovo

14 Use adequate lighting for the type of work you are performing. Use the monitor brightness, contrast, and image adjustment controls, if equipped, to optimize the image on your screen to meet your visual preferences. Keep your monitor screen clean so you can focus on the screen s contents. Any concentrated and sustained visual activity can be tiring for your eyes. Be sure to periodically look away from your monitor screen and focus on a far object to allow your eye muscles to relax. If you have questions on eye fatigue or visual discomfort, consult a vision care specialist for advice. Quick tips for healthy work habits The following information is a summary of some important factors to consider to help you remain comfortable and productive while you use your computer. Good posture starts with equipment setup: The layout of your work area and the setup of your computer equipment have a large effect on your posture while using your computer. Be sure to optimize the position and orientation of your equipment by following the tips outlined in Arranging your work area on page 2-1 so you can maintain a comfortable and productive posture. Also, be sure to use the adjustment capabilities of your computer components and office furniture to best suit your preferences now and as your preferences change over time. Minor changes in posture can help avoid discomfort: The longer you sit and work in front of your computer, the more important it is to observe your working posture. Avoid as summing any one posture for an extended period of time. Periodically make minor modifications in your posture to help deter any discomforts that might arise. Make use of any adjustments that your office furniture or equipment provide to accommodate changes in posture Short, periodic breaks help ensure healthy computing: Because computing is primarily a static activity, it is particularly important to take short breaks from your work. Periodically, stand up from your work area, stretch, walk for a drink of water, or otherwise take a short break from using your computer. A short break from work gives your body a welcome change in posture and helps to ensure you remain comfortable and productive while you do work.

22 Selecting a supported display mode The display mode the monitor uses is controlled by the computer. Therefore, refer to your computer documentation for details on how to change display modes. The image size, position and shape might change when the display mode changes. This is normal and the image can be readjusted using automatic image setup and the image controls. Unlike CRT monitors, which require a high refresh rate to minimize flicker, LCD or Flat Panel technology is inherently flicker-free. Note: If your system has previously been used with a CRT monitor and is currently configured to a display mode outside the range of this monitor, you may need to re-attach the CRT monitor temporarily until you have re-configured the system; preferably to 1920x1080 at 60Hz, which is the Native Resolution Display mode. The display modes shown below have been optimized at the factory. Table 2-3.Factory set display modes Addressability Refresh rate PAL 50Hz 640x350 70Hz 640x480 60Hz,66Hz,72Hz,75Hz 640x500 58Hz 720x400 70Hz 800x600 56Hz,60Hz,72Hz,75Hz 1024x768 60Hz,70Hz,75Hz 1152x864 75Hz 1280x Hz,70Hz,72Hz,75Hz 1360x768 60Hz 1440x900 60Hz, 75Hz 1680x Hz,75Hz 1920x Hz Understanding power management Power management is invoked when the computer recognizes that you do not use your mouse or keyboard for a user-definable period. There are several states as described in the table below. For optimal performance, switch off your monitor at the end of each working day, or whenever you expect to leave it unused for long periods during the day.
